They are still works-in-progress following a recent visit to Chicago. As the images shows, it's a test track so don't hold your breath, don't know when I'll be finished. Route building is a never ending process, especially urban settings with all those geometrical objects (buildings) that need to be just right or else they look awful.
 
Look at Chicago Metro 2.2 on the DLS that route is a good representation of the Chicago CTA, be something there you can use for personal use or with the authors pemission for other uses.
